Find the mean deviation about the mean for the following data

Question:

Find the mean deviation about the mean for the following data

Solution:

we make the following table from the given data:

Therefore

$\overline{\mathrm{X}}=\frac{\sum_{\mathrm{i}=1}^{6} \mathrm{f}_{\mathrm{i}} \mathrm{x}_{\mathrm{i}}}{\sum_{\mathrm{i}=1}^{6} \mathrm{f}_{\mathrm{i}}}$

$\frac{12500}{100}=125$
